Junctional Bradycardia

Inherent Rate: less than 40 beats per minute.

Most common junctional rhythms are JER, JR, IJR having an inherent rate of 40-60 bpm. P wave is inverted before or after QRS and can be hidden or burried in QRS, QRS is present, T wave follows QRS.

i work in the ICU and this is what im seeing every day..

[gigi14becay]

no p wave and bradycaria

@crist1819 in junctional rhythm p wave is negatively deflected or none

lol nice scary music

P waves in Junct...all inverted.

Where they are depends on where initiation of the impulse in the AV occurs.

Think of the AV divided into 3rds.

Top 3rd: impulse closer to the atria. It will depolarize before the QRS. So: P wave inverted before QRS.

Middle 3rd: impulse same distance from atria and ventricles. Both depolarize at same time. QRS is stronger and hides the P wave. P wave buried.

Lower 3rd: impulse closer to ventricles. QRS depolarizes 1st. So: P wave inverted after QRS.

Cheers!

@AJAXKID123 thancks for your response

@crist1819

The P wave is either inverted before the QRS, buried in the QRS or inverted after the QRS. It depends on where, in the AV the impulse was initiated.

Of course, after 8 months (which I just noticed) I'm sure you've long since figured this out :D

@ffe225 It may manifest as a sick sinus syndrome thus bradycardia dizziness n syncope....although i agree it is knwn as junctional rhythm n not junctional bradycardia
